' HEAT ABSOBBI'NG AND RADIATING, APPARATUS.

Application filed January 22, 1924. Serial No. 687,882.

To all whom it may concern: I

Be it known that I, NICHOLAS J. ZUZULIN, a citizen of the United States,residing at Minot, in the county of Ward and State of North Dakota, haveinvented certain new and useful Improvements in Heat Absorbing andRadiating Apparatus, of which the following is a specification.

My invention relates to furnaces, and has particular reference to thefire box construe provide a fire box for a furnace, such as a steam orhot water boiler, having means for storing heat in the upper portion ofthe combustion. chamber, so that the combustible gases escaping from thefuel, such as lignite, are properly burned. I

A further object of the invention is toprovide means whereby thecold airrushing into the fire box or combustion chamber,

upon the opening of the door for theintroduction of fuel, is heatedprior to passing to the tubes of the boiler, whereby they are notreduced in temperature, as frequently ocours with the ordinary boiler.

Other objects and advantages of the invention will be apparent duringthe course of the following description.

In the accompanying drawings, forming a part of this specification, andin. which like numerals are employed to designate like parts throughoutthe same.

Figure 1 is a central vertical longitudinal section through a boilerembodying my invention.

Figure 2 is a transverse section taken on line 2-2 of Figure 1, and,

Figure 3 is a horizontal section taken on line 3--3 of Figure 2.

In the drawings, wherein for the purpose of illustration is shown apreferred embodiment of my invention, the numeral 5 desig natescombustion chamber of a boiler, having the usual crown sheet 6. Arrangedbeneath this combustion chamber is the fire box Y, having a grate 8,beneath which is the ash pit, as shown. The combustion chamber 5discharges into the rear ends of fines or tubes 10, held within a shell11, for holding the water, as is well known in a hot water furnace. Theinvention is also applicable to a steam boiler construction. The numeral12 designates a door for the combustion chamber and fire box, and 13 isa door for the ash pit.

The invention resides particularly in the provision of heat absorbingand distributing means, arranged within the combustion chamber 5. Suchmeans embodies a plurality of arches or. inverted U-shaped ele ments 11, 15, 16, 17, 18 and 19. These elements are substantially identical inconstruc tion, but vary in height, and somewhat in shape. Each elementembodies an inverted U-shaped rod 20, the lower end of which is embeddedin the side walls 21 of the combustion chamber. Arranged upon each ofthese inverted U-shaped rods are a plurality of heat absorbing andreleasing memhers or blocks 21, such as fire bricks. It is preferredthat these fire bricks be rough and porous in order that they will morereadily absorb the heat and radiate the same. The fire bricks 21 havecentral openings formed therein, for the reception of the rod 20. These.fire bricks are suitably spaced upon the U-shaped rod by asbestosspacing collars 22, asshown. The fire bricks are held upon the rod,against displacement, by frictional engagement therewith, or by anyother suitable means. In the arched portion of the element produced bythe fire brick, the lower edges of the fire brick; preferably contact.As clearly shown in Figure 1, the element 18 extends above the element19, while the element 1.7 is below the element 18 but above the element19. The element 1.6 extends above the element 17 while the element 15 isbelow the element 16 but extends above the element 17. The element 14extends above the element 15 and the element 16. A staggered steppedrelation is thus produced at the tops of these elements, with acombustion chamber occurring above the adjacent intermediate element andbetween the ends of the two elements upon opposite sides thereof.Attention is called to the fact that the elements 14;. 15, 16, 17, 18and 19 are spaced, providing vertical passages which lead into thecombustion chambers or pockets 2 1, as shown.

In view of the foregoing description, it will be seen that coal isignited in the fire box 7. and when lignite is used, the com hustiblegases pass from the fire box 7 upwardly through the passages 23, andenter the combustion box 24-. The heat stored in the elements or arches14 causes these combustible gases to be properly ignited. Then the door12 is opened for the introduction of fuel into the fire box, cold airrushes fit) , means for storing heat, and radiatin same at the propertime, thereby retaining into the fire box, but this cold air passingupwardly'between and about the heat retaining and radiating elements, isproperly heated before it reaches the tubes 10 whereby these tubes arenot reduced in temperature. The arches or elements serve asha t e thetemperature of the furnace substantially even, in addition to effectingthe combustion of the gases, escaping from the fuel.

It is to be understood that the form of my invention herewith shown anddescribed, is to be taken as a preferred example of the same, and thatvarious changes in the shape, size, and arrangement of parts may beresorted to, without departing from the spirit of my invention, or thescope of the subjoined claims. a

Having thus described my invention, what I claim is:

1. A furnace including a combustion chamber and a fire box at the bottomthereof, and a plurality of upstanding arches arranged within thecombustion chamber and longitudinally, spaced therein providing upwardydischarging passages for the combustible gases, the tops of the archesbeing arranged in staggered relation affording combustion pockets incommunication with said passages, said combustion pockets being arrangedat different elevations, each arch embodying an inverted U-shaped rod,and a plurality of earthen blocks strung upon the arch and held thereonin spaced relation.

2. A furnace including a combustion chamber and a fire box at the bottomthereof, and a plurality of upstandin arches arranged within thecombustion ciamber and longitudinally spaced therein providing upwardydischarging passages for the combustible gases, the tops of the archesbeing arranged in staggered relation affording combustion pockets incommunication with such passages, said combustion pockets being arrangedat different elevations, which elevations are lowered toward thedischarge end of the combustion chamber.

3. A furnace including a combustion chamber and a fire box at the bottomthereof, and a plurality of upstandin arches arranged within thecombustion c amber and longitudinally spaced therein providing u wardlydischarging passages for combustible gases, the tops of the arches beingarranged in staggered relation affording combustion pockets incommunication with said passages, said combustion pockets being arrangedat different elevations which elevations are lowered toward the discharend of the combustion chamber, each arc embodying an inverted U-shapedrod, and a plurality of earthen blocks strung upon the rod and heldthereon in spaced relation.

In testimony whereof I afiix my signature.

NICHOLAS J. ZUZULIN.
